What is end behavior in the context of graphing functions?

Back

End behavior describes the behavior of the graph of a function as the input values (x) approach positive or negative infinity.

How do you determine the end behavior of a polynomial function?

Back

The end behavior of a polynomial function is determined by the degree of the polynomial and the sign of the leading coefficient.

What happens to the graph of a polynomial function with an even degree and a positive leading coefficient as x approaches infinity?

Back

As x → ∞, f(x) → ∞ and as x → -∞, f(x) → ∞.

What happens to the graph of a polynomial function with an odd degree and a positive leading coefficient as x approaches infinity?

Back

As x → ∞, f(x) → ∞ and as x → -∞, f(x) → -∞.

For the function f(x) = x^2 + 5, what is the end behavior?

Back

As x → ∞, f(x) → ∞ and as x → -∞, f(x) → ∞.

What does it mean if a function's end behavior approaches a constant value as x approaches infinity?

Back

It means that the function levels off and approaches a horizontal asymptote.
